I had a. Profile file that I was reading and using aliases from in my terminal, but at some point the aliases stopped working for no clear reason (other commands were still working).

To generate and realize 4D guidance in the terminal area, first there should be ground track , then the altitude profile and appropriate speed profile along the track.

In the Terminal Area energy Management, take advantage of the Energy-Range profile to achieve the flight control of Reusable Launch Vehicle and the energy is also controlled.
